No true.  Linux quotas support both soft and hard limits, though I never set 
soft to anything but the same value as hard, personally (some do and it is 
useful).

Which points out that quotas are not needed at all if you just do per-project 
LVs.  When they need space, run lvextend and resize the filesystem.  That's 
it and you don't have to unmount anything.
